Foo Fighters have released a free EP, titled "Saint Cecilia," which they dedicated to the victims of the recent Paris attacks.

The band has been counting down to a big surprise on their website for the last month, finally revealing the new album on Sunday, according to USA Today.

Last month, as the group prepared to headline Austin City Limits, they spontaneously decided to record some songs. Front man Dave Grohl said he wanted to offer these new tracks as a way "to give to the world as a 'thank yo' for the last 2 years."

The band set up their own makeshift studio at the Hotel Saint Cecilia and recorded five songs, including "The Neverending Sigh," Iron Rooster," "Savior Breath," "Sean" and the title track.

Guest contributions on the EP included Gary Clark Jr., Preservation Hall Jazz Band and Ben Kweller.

Grohl wrote in an open letter how the EP has "taken on an entirely different tone" since the Paris terror attacks occurred earlier this month. In dedicating the EP to the victims of the attacks, he said the offering was a "celebration of life and music."

While the EP can be streamed on Spotify, it is also available on the band's website, which also includes links for visitors to donate money to the victims of the Paris attacks.

A description of the EP on iTunes reads, "This five-song EP captures nearly forgotten moments from the band's 20-year odyssey - a brilliant patchwork of pieced-together riffs and song fragments that were tracked in an impromptu studio at Austin's Hotel Saint Cecilia. The road-tested band blasts through the set of scrappy guitar-driven rockers with high-volume fury. Polished? No way. But the rowdy performances and rough edges make Saint Cecilia pack a visceral punch."

 The Paris attacks forced the band to cancel the remainder of their European tour.
